This invention relates to means for and method of producing charts and graphic representation of studies ofevents where the relation ofcertain acts or distribution of comniodities to other acts or distribution of commoditiesof a similar nature are desired. 7

Enlarge business and government organizations, it has become a necessity. in presentation of conditions before executives to make .graphic studies which show at a glance the conditions which have been studied. Examples of these conditions whichfare to be represented are commodities handled, monies received and disbursed and petroleumproduced and distributed; in the means for graphically illustrating these conditions, in common use, it icesof the skilled analyst, but ices of a skilled draftsman, after whichthe charts or other productions are reproduced in multiple. in case of daily or weekly change, vnew charts have to be made or erasures made on the charts already constructed.

Figure 6 represents the adaptation of the invention to the study of the exports from the United States for the year 1928 and is a view of a direct process photographic reproduction of the device after the completion of the graphic analysis.

My invention is adapted for use in practically all business and social endeavors, in fact where any study of conditions may be desired to be illustrated in a graphic form. These conditions which may be set forth are 01" various types. They may be percentages, commodities, as barrels of petroleum, or monies in dealing with fiscal matters.

Reference is made to my copending; application Serial Number 361,215, filed ll/lay 7 1929.

In order to make the scope of the invention clear, a number of specific applications of the invention will be called to attention.

In governmental work in its application to the-work of the Commerce Department, one use is in the representation of the sources of production and importation of raw materials as compared with the distribution of the same, including exportation, for its destined use. I

These conditions may be set forth in terms of the percentages, dollars involved, or in the units of production. Another use is in the illustration of the monies earned from the several sources as compared with the expenditures which were made for other commodities. It is useful also to illustrate the fiow of any of the commodities which are studied by the Census Bureau.

In the Forei n and Domestic Commerce Bureau, the studies of exports and imports may be represented by this invention.

As applied to War and Navy Department activities, the invention is useful in studying mobilization and distribution, also procurement and supply.

In the analysis of the production and dis tribution of petroleum products and other mineral products, this invention lends itself to the use of the Bureau 01" Mines.

In the fiscal branches of the government, the incomes and expenditures may he represented by my invention and complete analysis quickly made.

use of this invention will save both time and equipment as the same material is used repeatedly.

In carrying out my invention in one form, I use a board 20 which may be made or" any suitable material and of all one piece or in sections, 20, 20 20 and 20 The board 20 is rovided with small holes 2O over its surface, preferably in rows one eighth of an inch apart, the holes of the rows being also one eighth of an inch apart. lhese holes are for the purpose of inserting small pins or pegs 20 for a purpose to be later described.

A flexible-strip bundle 21 is composed of any suitable material of contrasting appear ance characteristics relative to the board. If the board is made oftransparent, translucent or white or light material, then the material composing the bundle should preferably be of a dark color. If however, the board he of wood painted black or similarly appearing nateria-l then the fiexiblestrip bundle can be of white or light material.

The bundle 21 should be composed of strips which are separable throughout a substantial portion of their length in order that groups of these strips may be used to represent a weight or evaulation in the chart as will la ter clearly appear. As illustrated, the bundle 21 is composed. of tain white strips of cardboard of suitable length and of substantially onehalf inch in width. The bundle as used, is placed so that the strips stand on edge-with the edges adjacent the surface of the board. The board in the embodiment illustrated is a wooden board painted aflat black as shown in Figure 1.

A convenient way of carrying out the process of graphic representation with this invention is to select a sulliciently wide bundle oi flexible strips representative of the value of the total conditions to be represented. F or example, if the total amount of money to be represented on the chart were 500,000 dollars, a bundle of 500 strips might be selected. Then in this analysis, each strip would have a weight or value of 1,000 dollars. I)": the conditions to be represented and analyzed were percentages, a bundle of 500 strips might be selected w ierein in the analysis, each strip would represent two tenths of one per cent.

To assist in the selection of the correct size ot the bundle, it has been found desirable to provide a means having a different appearance characteristic at the end of a multiple of the strips, for example, each tenth strip may he of a dilierent color or have a marking on as shown at 21. If two hundred strips are found to be the correct number, then it only necessary to count twenty groups of ten strips and the correct number of the groups, during separation, is easily determined.

For the sane of clearance in illustration and description, I have indicated certain parts in Figure 2 which is a direct proces moto ra 3h of Fi ure 1 wherein is shown the l study set up on a black backgroundas done in the preferred way; These indications on the figure showing the photographic reproduction or" the study, it run he understood, refer to, parts on the actual study which cannot be well shown on the black background.

Having selected a bundle of the correct size, it is pla'cedon the board, the edges upward. The order of arrangement of the parts on the board is immaterial as to results. It has, however, been'found to be convenient, in

makin studi s of the eneral t 1 e to be described, to secure the strip bundle'adjacent its middle by the guides 23. I These guides, two in number, are placed oneach side of the bundle andin closerelation thereto. lhe guides have' curved ends to make gradual bends in the strips-whenthe same are divided in'groups, as will later clearl appear. These guides are secured inplace y the-use of securing pins or pegs 23 the latter being in.- ser ted in available holes in 'the board 20.

Let us assume that it is desired to make'a graphic chart ofthe oil supply of the country for the year 1928 as to its sources and destinations,showing the various places from which the oil supply is taken and the-various,

placesto which it goes.

in selecting the size of bundle,1 have selected 500 strips, each 25thstrip having sepaate appearance characteristics. Each strip tl'ius represents two tenths of l0'percent of the whole or approximately 3,000,000 barrels of oil.

' The correct size bundle of strips 21 having been selected and secured in'plac'eby the guides23 as above describedfthe sources of the oil supply will be first considered.

The first great group is the total stocks on hand at the beginning of the year. This is divided into two divisions, the crude products and the refined products. The crude products are'divided into three groups, (1) at'refine m the pipe line stocks and the ll ornia storage stock.

From the left side of the strip bundle, the appropriatenumber; of strips are separated indicatethe total num er of barrels of crude oil on hand at the beginning of the ar. These strips'are then bent at the side and thenstraight as shown at 25. Pegs are now used along the edge of these strips to hold them in place. At the outer left edge of the bundle an appropriate num ber of stripsare separated'as at 26 torepresent the amount of crude oil (1) at refineries.

as shown at 24 Similarly a group of strips is taken of an appropriate size to indicate the number of barrole of crude oil as at 27 and an'additional group to represent the California storage'stock as in'the pipe line stocks O 48. These groups are all secured in position by inserting pegs 1n the appropriate holes in the -1 ooard.

3 In order to represent the refin Products into si-ib groups to indicate the sources of im- 'The entire remainder of the strips of the i oil, I have first group hi l sform' apart of the total stock 'on hand at the beginning of the. year, an additional group of strips ota'n appropriate size issepa rated at the upper end of the bundle. .lThis group which I have secured in place by pegs. At 30, appears the graphic representation ofithe total stock on hand at the beginning of the year. g V

" Another source of supply-"for the country designated .29, is then is in the imports. This I have representedat g 31. This group 31 is of an appropriate slze and is'separated atfth'e-upper end from the main bundle-and is secured in place by 'the pegs already described.

The import group 31is'also subdivided ports as at 31 from Venezuela, 31' from C0". lornbia, 31 from Mexico'and 31 from all other foreign countries.

bundle'represent thetotal production for the year. At the. upper ends of the strips, groups 111 this total production remalnder, areseparated into the geographical sub-divisions as the destinations.

ln'order to indicate the distribution of the divided it into three groupsThe is the crude oil on hand at the end of the year, as shown at 38; the second is the part of the oilwhichhas passed to the stills .as shown at 40 andthe third are the exports of crude oilas shown at 41.

In the group'of oils on'hand, we have three sub-divisions, the representations of the amounts of oils at refineries as shown at42, (2) thepipejline stocks, as shown at 43 and'(3) the Californiastock as shown v at 44. U

Aside from the losses in refining which is shown at 39, the oils which are represented as having gone tothe stills are in six sub groups of strips indicatingthe productsas (1) gasoline,'shown at 45, (2) gas oil and fuel oil as at 46, lubricating oil, as at 47 (4) kerosene, as at 48, (5) unfinished prod:

It is to be noted that a portion of the gaso 4 line is sub-divided as naturalrgasoline, the remamder being refined. The former is nesignated byl the character It will also be seen that a-portion of the gasoline is exported.

theflndiana group. The Rocky ucts, as at 49, (6) 'WaX, coke and asphalt e This representation has been designated by the character 4",

The rep esentations of all of these destinati'onlqu eseparateu from the lower end of the bundle and. separately placed and secured by pegs as already described for the source groups.

In order to show the ends of the strips in the finished representation as ending at the desired place, I place over the ends of the strips, a piece of paper or other flexible material which preterabl" has the same general appearance characteristics as the board, In this way when photographed, as will be later described, the appearance on the photograph indicates that st has had actually ended there. See the dotted lines indicating the flexible cover material at 51.

In the use of the device I have found it a convenience to use strips in separating groups and sub-groups as shown by the dotted lines at 52. These strips are preferably made of Wood or other light material and are painted or otherwise colored to give the same appearance characteristics as the board. For exam ple, if the strips are of wood, they may be painted a dead fiat black, ii"- the board is so painted. The strips may be made of." various lengths and widths, it being usually unnecessary to have more than one thickness.

A feature of the graphic representation made with my invention, is that certain relations are plainly visible upon inspection. F or example, it it is desired to have a visual comparison between the total crude stock on hand Ja uary 1, 1928 and the total crude nand January 1, 1929, one glance stock on at the two bands the total crude representations shows clearly the stock on hand on Jonary 1, 1928 only slightly less than the total crude stock on hand January 1. 1929.

In this connection, attention is called to the fact that the multiple-indieating lines assist in this visual comparison.

In carrying out my invention, I have found it convenient to have the board and the other parts, not desired to show in the diagram, of black as already described and to have the bundle of strips of white material.

The advantage o l this is that when the whole is photographed, which is the next and final step, a black and white print may be made directly with the black diagram showing on a white background. This permits the use of ordinary photographic methods to produce the white background print without going through the step of making a negative.

An advantage of this invention is that the same equipment may be used, the graphic representation being changed each day or hour, if necessitated. The changes do not involve either erasures or destruction or replacement of any of the equipment. If a complete record is needed, aphotograph or photographs may be made at regular time intervals or whenever a change is made. If it should be found, in some instances, that a large number of prints are needed, a negative print may be made from the first directly made positive print and then other positive prints made.

In Figure 6, I have illustrated a study of the total exports from the United States, of merchandise to principal countries throughout the world during the year 1928.

As I have clearly described the detailed process and method of use of my invention; in describing this adaptation to a map, I will, for the sake of clearness and brevity describe the use with the map, by showing the completed photographic copy of the study. This is done for the reason that in the present preferred form, I use a black board which is diflicult of illustration in a drawing. The features will be indicated in Figure 6 and it will be understood that these are used with the board when the study is being set up.

Since the distances travelled are not taken into account and since the relative positions of the countries do notmatter in such a study, I have, for the sake of clearness, separated the map of North America into three parts.

These separated parts have been spaced to better illustrate the experts for the size or" map used.

Let us assume that of the exports from the United States for the year 1928, there are three principal sources-about 13% from the food producing industries, 25% from the textile industries and 25% from the machinery manufacturiesthe other 37% or the exports being from miscellaneous industries.

In the study illustrated, the sources of the exports, that is from the different industries, have been indicated by white strips, the exports over the Atlantic routes by green, over the Pacific routes, by red and to Canada by blue.

In setting up the study maps, the maps of Europe, Africa, South America, Asia, Australia, Canada and Mexico were placed upon the black board which as photographed directly appears as a white back-ground at 220. This black board is in four sections as indicated at 220*, 220", 220 and 220 and is provided with small holes in its surface as already described for the board 20.

The maps of Canada and Mexico are shown as being separated for the purpose of clearness.

In the construction of the export sources indications, two hundred was the number of strips arbitrarily taken, there being one black strip placed as the twentieth strip and each multiple of twenty. This places one black strip to indicate the boundary of each 10% of the exports. In indicating the sources, the two hundred strips were bound together as indicated at 221 and secured in place at a point to be occupied by the map of the United States, as at 222., 'l I The appropri te number of strips at the outer end are separated, as at'223, to represent the 13% of thewh'ole U. S. e'xportsfor the year. This 13% of the whole represents the food products exported from the United States during the year.

These are bent as shown and black'strips placed on each side to destroy shadows and reflection. These strips are now secured: in place by means of the pins in coaction with the walls of the holes in the board.

An appropriate number ofstrips to indicatethe textile products exports .which are 25% of the whole exports, is now separated at the outer end of the strip bundle. After shielding the strips with black strips to de stroy the reflections and shadows, the separated bundle section is pinned in its place as shown at 224. I

This operation is repeated for the strips to represent the machinery exportsand for the miscellaenous exports as shown" at 225 and 226, respectively.

The sources of the exports as to manufao ture, have now been indicated; As white strips are used for these source indications, they willshow dark or black on the photo graph in direct processes. I

In order to show the relation between the different exports and their destinations, I

select the same number of strips as wereused in the sources indications. These two hundred strips with each twentieth strip, a black one, are bound togetherat one end to form a bundle and the bundle placed on the'board This bundle to show the use of the colors in using strips, is in three color groups. Blue strips are used toindlcate exports to Canada,

red strips are used to indicate exports to points on the Pacific,-including Mexico and green is used to indicate exports to all points on the Atlantic, including Europe, Africa and all Atlantic ports of South America. In

the photographic process, these colors show of difierent shades and may easily be differentiated.

After the end of the strip bundle has been put in place, it is suitably secured by placing the pins at the sides inthe holes in the board. The map of the United States is now placed in place over the abutting ends of the strip bundles and suitably secured in place, as by pins. These two bundles when in position become a single bundle in two parts, for the purpose of the study.

In forming that portion of thewhole bundle to represent the destinations of the exports, the divisions of the colored strips are made so that the proper number of each color will be provided in the respective groups. p

The free ends of the strips are now separated into their groups to rep'resent'the exports to the several destinations andare stripped with black "strips at their and secured in proper place to indicate the proper destination.

represents the exports to South Africa, the

group' 233 represents the exports to the Argentine Republic and the 'groupfl23t, the exportsto Brazil.

On "the Pacific side, the red strips of the .bundle are divided proportionally to the exports to the se'vera-l'principal countries,'the group 235 representing the exports to Mexico, the, group 236 'representingthe exports to -Central American countries, the group 237 representingthe exports to Colombia, the group 238, to Chile, the group 239, the exports to iexustralia, the group 240, the exports to New Zealand, the group 241, the exports to China and the group 242, the exports to Japan.

The blue group designated 2 l3,'repres ents the exportsto Canada. f i

All of these groups are provided with pins to hold them in place, the pins being inserted in the holes of the board 220'as earlier'de scribed. They are also provided with black strips on their sides to eliminate shadows and reflections.

In order to provide shields for the ends I of the strips, map sections maybe raised 7 above the strip ends as injthe case of the map of the United States shown at 227 and which is illustrated as over the ends of the strips which form the two'sections of the whole strip bundle. V V
